Description

These PAC Racing Springs PAC-R649-16 valve spring retainers are crafted from tool steel with an ultra-lightweight design. They feature an 8-degree lock angle and are designed for dual valve springs with a 1.200-inch outer diameter and a 0.775-inch inner spring OD step. Advanced processing, including micro polishing and Nano Peen technology, enhances lifespan and wear resistance due to the steel's high hardness.
